i Application {iled June 27, 1905. Serial No. 267,219.

To rz/ZZ whom, t r11/ay concern:

Be it known that I, CHARLES CHABAU, a citizen ofthe United States, and aresident of New York city,borough of Manhattan,in the county and Stateof'New York, have invented a new and Improved W'indow, of which thefollowing is a full, clear, and exact description.

This invention relatesto improvements in windows of the class designedto be swung into a room for the purpose of conveniently cleaning theouter side of the glass, the object being to provide asu pplementalswinging casing in which the upper and lower sash are arranged to slideand whereby both sashes may be moved together' to the inner side of aroom for the purpose above mentioned.

I will describe a window embodying my invention and then point outthenovel features in the appended claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similarcharacters of reference indicatecorresponding parts in both figures.

Figure 1 is a side elevation of a window embodying my invention, partsbeing broken away and in section; and Fig. 2 is a section on the line w:v of Fig. 1.

Referring to the drawings, l designates the main window-casing, and 2the supplemental or sash-carrying casing, havingswingingconnection withthe main casing. As here shown, the supplemental casing has hinges 3,connecting with a spacing-board 4, rigidly secured in the main casing.Arranged to slide between the free side of the supplemental casing andthe adjacent side of the main casing is a stop-board 5, which when thesupplemental casing is closed will prevent the entrance of air, dirt, orthe like; but to swing the supplemental casing-inward the said stopboardmust be removed. The stop-board is held in place by means of bolts 6,which pass through openings in the supplemental casing and openings inthe stop-board and have their threads engaging with threaded socketmembers 7- in an upright of the main casing. These fastening-bolts areprovided with iinger-pieces 8, so that they may be readily inserted orremoved.

The operation of the device is quite obviouse-that is, when it isdesired to swing the supplemental frame inward for the purpose ofwashing the outer side of the windowglass the bolts 6 are to be removedand the stop-board 5 drawn out., so as to permit the sash-carrying frameto swing in the are of a circle. Y

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. In a window, the combination with a main casing,of a sash-carrying casing mounted to swing in the mainY casing, and astopboard for sliding between the free side of the sash-carrying casingand the main casing.

2. In a window, the combination with a main casing, of a sash-carryingcasing mount-` ed to swing in the main casing, a stop-board for slidingbetween thefree side of the sashcarrying casing and the main casing, andmeans for securing the said stop-board in place.

3. In a window, the combination with a main casing, of a supplementalcasing mounted to swing therein on a horizontal plane, a Stop-boardadapted to slide between the sashcarrying casing and the main casing,and bolts for passing through the main casing and the stop-board andengaging with an upright of the main casing.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
